Collation conversion utility

I have taken a backup from SQL server 2008 R2 and restored it in SQL server 2014. Now the database collation is SQL_Latin1_General_CP1_CS_AS. I have to change the collation to Latin1_General_100_CS_AS_SC. When I run the collation conversion utility, it prompted to enter the details like destination host name, instance name, db admin user name, db user name, default db and application name. When I enter all the details and hit the enter button, the window closed. Nothing happening. Please give me a solution as soon as possible.
